Life A comprises decapsulated artemia cysts, which can be hatched in the same way as encapsulated cysts. The hatched nauplii are shell-free, and in consequence there are no waste shells to remove. This shell waste, if ingested, can cause serious problems for juvenile fish and they may die due to constipation. Because life A is de-capsulated, it is an excellent food for raising seahorses. Available in 250 ml size.
